After updating a pack in the Marketplace everything froze. Buttons were unresponsive, would light up, and no noise would play, much in the same way as when you drag a finger across a button and don’t press it. To try to fix it, I left the app (didn’t quit it) and re-entered it. After a brief loading screen, this popped up and endlessly glitched. The original screen recording was 19 seconds long, but I had to cut it down to meet the file size requirements. (Just an explanation as to why it’s so short).
